different behavior with npm and pnpm

[sdavids]

Setup

$ mkdir /tmp/test && cd "$_"
$ npm init -y
$ npm i -D @playwright/[email protected] [email protected] [email protected]
$ jq '.scripts += {"lint":"eslint ."}' package.json >.tmp && mv .tmp package.json
$ cat <<'EOF' >eslint.config.mjs
import { flatConfigs as importConfigs } from "eslint-plugin-import-x";

export default [importConfigs.recommended];
EOF
$ cat <<'EOF' >playwright.config.mjs
import { defineConfig } from '@playwright/test';

export default defineConfig({});
EOF

npm

Run lint:

$ npm run lint

> [email protected] lint
> eslint .

With npm there will be no error.

pnpm

Get rid of npm stuff and install pnpm stuff …

$ rm -rf node_modules package-lock.json
$ pnpm --silent install

Run lint:

$ pnpm run lint

> [[email protected]](mailto:[email protected]) lint /private/tmp/test
> eslint .


/private/tmp/test/playwright.config.mjs
  1:10  error  defineConfig not found in '@playwright/test'  import-x/named

✖ 1 problem (1 error, 0 warnings)

 ELIFECYCLE  Command failed with exit code 1.

With pnpm there is an error.

I skipped providing a working playwright setup because it would just clutter this PR.
